BAJA Wet Cat analog delay (mini version)

The two 100K resistors on the Cancel trim go to ground on the 3205 DM-2.

Oh Shit

I will have to change that on the PCB too!
Doing that now

thanks Dan N

Hang in there, Bajaman. It's a cool fucking project! Thanks!

New PCB, Composite, and Component layouts just uploaded for MN3205 version - refresh your browser.
hopefully it will work now - my sincere apologies.

ok so only the mn3205 needed corrections and they are now correct, correct?

so when you go back to the post where baja's link to the boards layout, png's are then they are updated?

yes (hopefully

) but do not forget to press F5 to refresh your browser.

Does the OP275 have to be a OP275G, or could a OP275 be fine?

According to a recent post by Mr Huge, he only used the OP275 in a small number of his Aqua Puss delays on which the Wet Cat is based. You could use any dual op amp in this circuit. For example: TL072, 4558, OPA2134, TL082, TL062, etc.
Whether YOU here any difference, depends on how 'Golden' your ears are.

Did you switch the polarity of the diode on the MN3102 after wiring up the jumpers?
I tried switching the polarity of the diode, but still no change.

Hey WeAre138.
Did you ever get your delay working?

Not yet. I decided to etch a new board, since the traces were starting to pop loose from constant re-soldering, and I haven't been able to find the time to populate it yet. I should be able to finish it up about a week from now and I intend to give build report once it's up and running.

Here's my Wet Cat build #2 (both MN3005 ver) and it turned out pretty sweet I think. Some of the paint sparkles became visible through the print on the decal, don't know how that happened, but its a neat unexpected effect.

At one point I compared the Wet Cat layout to the AP schematic that was posted in the other thread and if I recall correctly, there is a 6.8n cap and a 10k resistor that should be switched around, its near the input somewhere. Also should that lone 1K resistor actually be a 10k? Either of those probably don't mean much if anything to the end result I'm guessing though.

I might try tweaking the impedence a bit as I find that there is a bit of a volume drop when I don't have put a buffered pedal in front of the delay.

Very cool appeareance. What did you use (decal) to make the printing?

sfx · Post by **sfx** » 03 May 2009, 06:11

Illustrator... Anything that does vector graphics i think

would work great.

Hi,

Beautyfull project

The scheme is the same of “aqua puss”?
For wiring the pots and list of parts?

Thanks

thank you Baja

Is the scheme and layout with mn3205 verified? Someone has built it successfully? Any problem to solve? Differences with 3005? thanks!!!!

on a scale from - "if you've made a fuzz pedal you can do this" to "you may have to purchase an extra brain",,, how hard was this to build?

Hi,

I've built the baja wet cat MN3005 version... but i have some troubles as it doesn't work.
i mesured voltage between 9V hole and ground and it's only 0.6 V.
I've checked many times the wiring. but i can't find where it comes from. i simplify the circuit for testing. the battery is directly plugged to the 9V hole. no switch, just 2 jacks.
nothing as burned, that's the only good thing!
Anyone can help me please?

i noticed some things on the layout. i believe M2 is M1 and F2 is F1, if i look at the schematic.
C36 and C37 are missing on the layout and ready-to-transfer pcb. Normal?

sorry for my english.

regards,

Ed.

Hi!
I´ve built the 3205 Version, but cant get any Delay oit of it. Dry signal is loud an clear.
Has anybody build this version succsesfully and can tell me the voltage for the 3205?
Thanks!
Chris
PS Sorry for my bad english...
